The only guys that wanna be friends with a girl are gay guys and guys that wanna get in their pants but are stuck in the friend zone. Which one are you?
If neither, then ask yourself what the fuck you are doing rt now.
I actually feel bad for this chick, here it is you guys are hanging out and she probably thinks something really great is happening, meanwhile you aren't attracted to her and are spending time because you feel bad for her. Dude, that shit is cutting, like painful and evil thing to do to a person. It's just fucked up you even got this far with it.
Now, let's say you stay with her and you aren't attracted to her, how long is that gonna last before you go out and cheat on her? Sex is a big part of a relationship, so if it's not there then stop lying to yourself or convincing yourself you even need to try making it work
